Situated at an altitude of 2350 m, this large building constructed in 1957 was carried away by an avalanche two years later. A witness to this is a concrete slab below the refuge. Rebuilt in 1966, it was definitively extended in 1978 with a capacity of 54 places. A stage of the Tour de l'Oisans (GR 54), it welcomes hikers in the summer season and provides a shelter in the winter; it belongs to the Club Alpin Français.

Just above the signpost, there are the ruins of a pasture shelter commonly called the, « jas ». Often built using dry stones, this kind of shelter was used to protect the flocks during the summer season.

Since the end of the ice age, water has carved the rock and the passage of materials has created a small gorge polishing the base rock (gneiss, micaschists). The National Park has taken on the challenge of building a wooden walkway for walkers to cross this gorge. 

Over a change in altitude of a hundred metres there is a covering of heather which provides pollen for the bees and purple colour in Autumn, A small persistent shrub with tiny leaves and little pink flowers, it is called Common Heather or False Heather.

At the beginning of the path, is a big waterfall that you can approach on a narrow footpath just before climbing the coast. Situated on Combefroide torrent at a rocky escarpment, this waterfall has several projections and presents a total drop of several dozen metres.

Hayfields surround the village of La Chapelle. Unfortunately, such natural hayfields, and their flowers and insects, are more and more frequently replaced by temporary hayfields, in other words, certain years they are sowed. These prairies are still watered by the irrigation canals that are well maintained by the users with the help of the National Park. You will see the floodway of the Grande Levée canal not far from the stream as it nears the Sèveraisse. The canals are of great importance for preserving wetland flora, such as alternate-leaved golden saxifrage or yellow star-of-Bethlehem, both of which are protected species.

Between La Chapelle and Le Clot, it is not rare to see the golden eagle flying over the sunlit slopes. In the summer, this majestic bird of prey with its dark plumage (some have lovely white rosettes on the underside of their wings) mingles with the short-toed eagle, which is smaller and lighter-coloured, and the griffon vulture, which is larger, with a short tail and often flies in groups. There is nothing surprising about this as the south facing slopes provides thermal lift that enables them to fly high and far.
